Unlike most states, the Massachusetts Health Connector has not only seen no net attrition since the end of Open Enrollment, but has actually seen a net increase in enrollment...mainly due to their unique "ConnectorCare" policies, which are fully Qualified Health Plans (QHPs) but have additional financial assistance for those who qualify and which are available year-round instead of being limited to the open enrollment period.

Therefore, depending on which number you use as your starting point, their enrollment as of June 1st is up either 5%, 7.5% or 13.8% to date, and currently stands at 223,778 effectuated QHP enrollees. More interestingly, if you look at the charts below, you'll note that even when you remove the ConnectorCare plans and stick to "standard" QHPs which can only be enrolled in during open enrollment for most people, the current enrollment number is still up slightly (around 1.5% since March, and up 5.1% since February), which I actually wasn't expecting.
